Hey there,
The word problem is as follows:
- t multiplied by 52 is the same as 349
In numbers this would mean t x 52 = 349. Now to solve for t we would do the opposite of multiplication which is is division.
So...
- 349 ÷ 52 = t and t = 6
The answer would be t is equal to 6 and
or 6.712
Hope I helped,

Answer:


So the best answer for this case would be:

Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the costs of unleaded gasoline of a population, and for this case we know the distribution for X is given by:
Where
and
We select a sample size of n =16. Since the distribution for X is normal then we know that the distribution for the sample mean
is given by:


So the best answer for this case would be:

Answer:
5,6,7
Step-by-step explanation:
Recall that r^2 = x^2 + y^2, so that r = sqrt(x^2+y^2).
y
r = 3 sin g becomes sqrt(x^2+y^2) = 3*-----------------------
sqrt(x^2+y^2)
Squaring both sides,
9y^2
x^2+y^2 = -----------------
x^2 + y^2
If this is correct (and I'm not convinced that it is), then (x^2+y^2)^2 = 9y^2
shows the relationship between x and y. Can anyone improve on this result?
Answer:
-20
Step-by-step explanation:
Absolute value is a number's distance from 0. It is always positive.
|-20|=20
|0|=0
|-10|=10
|10|=10
-20 has the greatest absolute value.
